Abstract (en)
An instrument ("INSTR") hardkey facilitates a change in settings of any instrument displayed in any of the windows that appears on a display. The user merely depresses the "INSTR" key and selects the instrument whose settings are to be changed by means of a softkey menu that is displayed when the "INSTR" hardkey is depressed. A color editor is preferably resident in the display and provides a superimposed window and softkey menu for enabling the user to adjust colors. An "Adjust Color" softkey allows the user to adjust one or all of six factors: red, green, blue, hue (tint), saturation (color or color level), and luminosity (brightness). The window preferably displays red, green, and blue bars in a bar graph format, which change in height as the user changes the red, green, and/or blue settings by means of a rotary pulse generator or a numeric keyboard. The window also shows readouts for hue, saturation, and luminosity which change as the user adjusts the values with the rotary pulse generator or the numeric keyboard. The ability to adjust any or all of the six attributes (red, green, blue, hue, saturation, and/or luminosity) enables the user to select any desired color. A method implemented in software, instead of hardware, also provides pixel stretching to the entire display to provide clearer, more refined images.
